GOVERNOR.

SPECIFICATION forming part of Letterslatent No. 237,655, dated vFebruary 8, 1881.

Application filed October 13, 1880. (No model.)

To all whom it may concern Be it known that I, EDWARD WRIGHLIO' Worcester, in the county ot Worcester and State ot' Massachusetts, have invented certain new and useful Improvements in Governors; and Igleclare the'followingo be a description of my said invention sufficiently full, clear, and exact to en able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawin'gs, which form a part of this specitication.

This invention relates to the peculiar construction and arrangement ot the tension and adjusting devices in a governor mechanism, as described, with a view to rendering the governor more neat, simple, compact, and convenient, and to provide a mechanism adapted for light or heavy work on steam-engines or water-wheels, and adjustable to any required speed.

In the drawings, Figure l is a side view of such parts of a governor mechanism as are necessary toillustrate the nature of myinvention. Fig. 2 is a vertical sectional view of the same at line a' x, and Fig. 3 is a horizontal section at line y y.

The part indicated by letterAis the revolving standard, spindle, or shaft, formed hollow through its axis and supported to revolve in a bearing, B, on the frame B,it being provided wit-h a gear, A', or other suitable means whereby it can receive the required motion from the driving mechanism in the ordinary manner.

At the upper part of the spindle A are formed ear-pieces or arms a a, to which are fulcrumed, at b b, the levers O C 'carryin g the balls or weights C', as shown.

D indicates the controlling-rod by which the steam-valve, cut-oft' devices, ratchet-guard, or other variable mechanism to be acted upon by the governor is connected, the connection being made to the lower end, 1,0f said rod, orin anysuitable manner, according to the position or use of the mechanism. The controlling-rod D is arranged through the center ot' the spindle A, and its upper end is connected for operation with the ball-levers C by means of a revoluble head, E, having side grooves, c, to receive the broad bearing ends c of said levers,

by which said head E, together with the rod 1'), is depressed or raised as the balls C'moveoutward and inward. The head E revolves with the levers C and runs loose on the rod D. or on the hardened-steel sleeve F surrounding said rod, and is confined between the nuts G and H, which are screwed onto the rod D respectively above and below the sleeve F, suitable washers, g and h, being introduced, so that, the bearing or wearing surface being on the steel sleeve and washers g h, the parts can run freely under heavy strains. This is of importance on governors used for regulating heavy water-gates, Ste. The nuts G H on the screwthreaded end ot' rod D permit of adjustment for varyin g the length of the connections when setting up or applying the governor to use.

I indicates the tension-spring for forcing inward the balls C' Vagainst their centrifugal action. Said spring I is coiled around the controlling-rod D within the hollow of spindle A, (which is made ample size for its reception,) and is strained for exerting expansive force, its upper end pressing against the collar or extension H', below the nut H, while its lower end rests within and is supported by astep or bearing tube, K', upon an adjustable arm, K, arranged to move up and down independent of the rod D. The collar or extension-sleeve H' and the step-tube K are turned ofi' to iit into and form bearings or journals in the upper and lower ends of the spindle A, the lat,- ter being properly reamed out for their reception. These bearing parts H' K' keep the rod D in centra-l position within the spindle A, while at the same time theycompletelyinclose the spring I within the central chamber, and thus give the mechanism a clean exterior and neat appearance. The parts I-I' and K' slide in and out of the spindle-H as the rodD rises and falls, K' as the spring support-bar K is adjusted,respectively. The adjusting-arm is provided with a support-rod, L, which extends up through the frame B', andis furnished with a hand-nut, L', by means of which the bar K can be raised or depressed for regulating the tension of the spring I and adapting the action ot' governor to greater or less speed.

By arranging the parts as herein described the governor is rendered compact and neat, a

IOO

single spring acts upon both of the balls uniformly, while adjustment is provided for the adaptation ofthe length ofthe eontrollingrod, and nn independent and ready adjustment of the tension devices for adaptation to the required speed. The governor is sensitive and quick in notion, simple in construction, and easily cleaned and eared for.

If desired to entirely protect the spring` l from Contact with oil, the tubes or parts H K can he elon gated or extended, so that the lo wer,

l', will telescope within the upper one, H.

This, however, is not essentiel to the proper operation ofthe devices.

l um aware that governors have heretofore been madewith their oontrollingrod arranged through :t hollow standard or spindle, and I do not claim suohi'enture as of my invention; neither do I claim, broadly, the use of springs for assisting the notion ofthe Weights or balls in governors. f

What I oleim es of my invention, and desire to secure by Letters Potent, is

1. In e. governor, the combination, with the ball-levers G and spindle A, of the spring I, inelosed within said spindle, the controllingrod D., passing through the sinne, the adjusting-bnr K, with screw-rod L and :nut L', and the bearing pieces or tubes H' and K', as tnd for the purposes shown and described.

2. In combination with the belllevers C, having; broad bearing ends c, and screwthreaded rods D,fo,r connecting the controlled meehanisni, the revoluble grooved head E, the steel sleeve F, and nuts G and H, for the purposes set forth.

W itness my hand this 21st day of September, A. n. 1830.
